部署时的飞路迁移：检测到对 close() 的非法调用
Flyway migration on deployment: Illegal call to close() detected
我们正在 GlassFish (3.1.2.2b5) 上构建 Java EE 6 .ear 应用程序 运行 并使用 Flyway (3.2.1) 来管理我们的数据库架构。这发生在部署 .ear 时 - 网络上有一篇名为 "Easy Database Migrations using Flyway, Java EE 6 and GlassFish" 的文章很好地概述了如何执行此操作。我们最低限度地采用了迁移器代码，本质上只有 changing/removing 一些日志记录：
@Singleton
@Startup
public class FlywayMigrator {
private final static Logger LOG = Logger.getLogger(FlywayMigrator.class.getName());
@Resource(lookup = "jdbc/myDS")
private DataSource dataSource;
@PostConstruct
private void onStartup() {
if (dataSource == null) {
LOG.severe("Cannot migrate, no datasource configured!");
throw new EJBException("Cannot migrate, no datasource configured!");
}
Flyway flyway = new Flyway();
flyway.setBaselineOnMigrate(true);
flyway.setDataSource(dataSource);
flyway.migrate();
}
}
现在的问题是，这在迁移方面非常有效 - 不能说完美。但是，它确实会导致每次在日志中打印三个相同的警告：

FlywayMigrator 的第 32 行 - 不出所料 - flyway.migrate(); 行。
我的问题是：我们怎样才能摆脱那些警告？我找到了 a very similar looking issue which happened on an older version of Glassfish (2.1.1), but no reason or solution is stated there。这不是关键任务，但希望这些警告消失，此外，了解它们的根本原因会非常好。
除了不允许 Flyway 扫描更新脚本之外，您可能无法摆脱讨厌的消息。被调用的代码（由 Flyway）看起来像这样
public void close() {
// nothing
_logger.log(Level.WARNING, "Illegal call to close() detected", new Throwable());
}
如您所见，Flyway 不是这里的罪魁祸首（对此您无能为力）
